ITPEC IP October 2025 Question 11
ITPEC IP October 2025 — Question 11 of 100
It can run the same operating system or applications as the original CPU — software compatibility is the defining property.
A compatible CPU implements the relevant instruction set and behavior expected by software built for the original processor. It may differ internally or be produced by another vendor, but software compatibility allows it to serve as an alternative platform.
Answer (a)
Why not others:
- (b) makes an absolute patent claim; compatible implementations can be licensed or designed without infringing protected inventions
- (c) incorrectly limits compatibility to single-core CPUs
- (d) incorrectly limits compatible CPUs to upgrades for old PCs; new systems may also adopt them
Key rule: CPU compatibility concerns observable architecture and software execution, not identical internal construction, core count, or product age.
